BIOS Setup
Introducti on
The purpose of this manual is to describe the settings in the AMI BIOS Setup
program on this motherboard. The Setup program allows users to modify the basic
system configuration and save these settings to CMOS RAM. The power of CMOS
RAM is supplied by a battery so that it retains the Setup information when the power
is turned off.
Basic Input-Output System (BIOS) determines what a computer can do without
acc essing programs from a disk. T his system controls most of the input and output
devices such as keyboard, mouse, serial ports and disk drives. BIOS activates at the
first stag e o f the booting proc ess, l oading and executing the operating syst em. Som e
additional features, such as virus and password protection or chipset fine-tuning
options are also included in BIOS .
T he rest of this manual will to guide you through the options and settings in BIOS
Setup.
Plug and Play Support
T his AMI BIOS supports the P lug and Play Version 1. 0A specific ation.
EPA Green PC Support
T his AMI BIOS supports Version 1.03 of the EPA Green PC specification.
APM Supp ort
This AMI BIOS supports Version 1.1&1.2 of the Advanced Power Management
(AP M) speci fic ati on. Power m anagement fe atures a re im plem ent ed vi a the Sy stem
Management Interrupt (SMI). Sleep and Suspend power management modes are
supported. Power to the hard disk drives and video monitors can also be m anaged by
this AMI BIOS.
ACPI Supp ort
AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power
interfa ce specifi cation (ACP I). It provides ASL code for pow er management and
device configuration capabilities as defined in the ACPI specific ation, developed by
Microso ft, Intel and Toshiba.
